T o all whom, it mag/*concern Be it known that I, RALPH S. SGHRUMN, a resident of Tarentum, in the count-y of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Feeding Mechanism for Tinning- Machines, of which the following is a speciyfication.

The prime object of m-y invention is to Figure 1, is a central longitudinal sectionalt view of an apparatus'. embodying my invention, the section being taken on line 1- 1 of Fig. 2; Fig. 2, a plan; Fig. 3, a front elevational view with a portion of movable platform broken away; Fig. 4, a longitudinal section taken on line IV-IV of Fig. 3; particularly showing the fork operating mechanism; Fig. 5, a side view of the movable carrier; and Fig. 6, `a rear elevation of the carrier. p

Referring to the drawings, 2 designates a liquid containing tank or feed box designed to hold in addition to the liquid, a pile of plates 3. As illust-rated, tank 2 is mounted on a car 4 which is designed to be run in'to a convenient position for the plates to be reached by the automatic feed mechanism.

The plates are preferably supported by an adjustable false bottom or rack 5 disposed in an inclined position by means of a series of ledges as 6 formed in a wall of the tank. By the employment of the adjustable rack 5 .and its sup orts, I am enabled to raise or lower the rac to properly position plates of different sizes.

7 designates a flux-box or a ortio'n of the tinning machine into which t e plates are to be delivered. As shown, box 7 is provided with guide-ways 8 and 9. Located over the tank is a pivoted frame comprising two side members 10 hinged to a support or a wall as indicated at 11 by means of clam s 12. Members 10 at their inner ends are e arged as shown at 13 and are connected b shafts 14, 15, 16, and 17. Fixedly secure to the `respective side parts of the carriage.

respective enlarged ends of members 10 and depending Atherefrom I provide slotted guldes 18. The forward ends of the members 10 in addition to supporting the shafts 14, 15, 16 and 17 support a rod 19 having its bearings in bent arms 20,the latter being pivotally connected with the enlarged ends 13. Y

21'designates guide arms for the moving plates and 22 rollers on rod 19.`

Mounted on shaft 14 I provide two rollers 23 between which and the rollers 22 the plates areadapted to pass on their travel to the tinning machine. Shaft 14 is also provided with three toothed pulley wheels 24 and with a wheel 25, the latter being designed to receive -a driving chain 26 extending from-a driving wheel 27 mounted on and adapted to rotate with a main drive shaft 28. Main shaft 28 is driven by any suitable means, as illustrated it is provided with a belt pulle 29 designed to receive a belt, not shown. haft 15 carries three loose guide pulleys 30 and. shaft 1.6 a corresponding number of pulley wheels 31. Shaft 16 is located in the slotted guides 18, directl below and in line with shaft 14` with the weels 31 thereon in line with wheels 24, and is designed to move vertically therein as hereinafter described. Cross-rod or shaft 17 is designed 'to support the'upperend of a movable skeleton platform 32.

Supported by members 10 and mounted on grooved wheels 33 I provide a movable carrier or carriage comprising two side parts with each part comprising a casting having a member 33 and two angular depending members 34 and 35 connected by shafts as hereinafter described. In addition to the parts mentioned, the carrier comprises two depending arms each comprising integral members 36 and 37, the arms being connected with the lower ends of members 35 by a. shaft 38 extending across and connecting lgclhe tending from one side part of the carriage to the other in addition to shaft 38, I provide shafts 39, 40, 41, 42, and 43 connecting said side arts. The wheels 33 are mounted on sha t 39 and said shaft 39 is provided with two gear-wheels .43, respective] adapted tomesh with and drive gear-whe@ 44 carried on the ends of shaft 40; three toothed pulley wheels 44", over which three `plate conveyer chains 45 extending from shaft 14 pass, and/with two nicked rollers or disks 46. Shaft 40 also has mounted thereon two rollers 47 between which and the rollers 46 the plates are passed, and a toothed .wheel 48. y Shaft 41 is driven by means of a chain 49 extending from wheel 48 over a wheel 50'mounted on shaft 41. Mounted on and movable with shaft 41 is a cam 5l the latter being designed to engage the free end of a `pivoted rod 52. Rod 52 is carried by shaft 43 and has a lower por-l tion 53 adapted to make contact with the outer` plate of the pile of plates 3. Shaft 38 located below and.slightly in advance of shaft 41 is connected with the latter shaft and driven by a chain 54 leading from a wheel 55 on shaft 41 to a wheel 55l on shaft 38.

56 designate rotative and bodily movable friction rolls adapted to successively engage at predetermined intervals successive outer plates of the pile of plates to be operated on. These rolls are carried on shaft 38 and move forward with the forward movement of the carriage. Located on shaft 42, which is located below and slightly to the rear of shaft 38, are two plate engaging friction rolls 57. Shaft 42 together with the rolls 57 are driven by means of a chain 58 eX- tending over wheel 5 9 on shaft 38 vand a wheel 60 secured to shaft 42. Rolls 57 like rolls 56 are arranged to be moved into contact with the outer plate of the pile of plates and away from said pile at predetermined intervals and the means as illustrated for bodily moving said rolls, comprise the cam 51 and the pivoted rod 52. The lower portion 53 of rod 52 is designed to fall into contact with thesucceeding outer plate as soon as the outer plate of the pile is moved by the friction rolls, above the portion 53, but the cam acting against the free end of rod 52 moves said friction rolls away from the pile of plates and prevents the rolls acting to force the succeeding plate upwardly until the plate previously moved has reached the conveyer chains 45. It will be noted that as the pile of plates diminishes, the carriage is moved forward and in order to take up the slack in the conveyer chains 45 the shaft 16 is moved downwardly in its slotted guides. Suitable guidepieces 61, 62 and 63 are provided on the carriage designed to guide theplates between the rollers 46 and 47 .on shafts 39 and 40 and onto the conveyer chains 45.

The movable platform 32 connected with cross-rod 17 at one end extends downwardly in an inclined direction to near the HuxboX and is provided with downwardly eX- tending bent arms 64 rigidly `connected with the platform having their lower ends connected by a pin 65. Pin 65 and the arms are raised by means of a cam 66 carried on main shaft 28, and the platforms being rigfork is moved forward toward the machine' by mechanism comprising an upwardly extending arm 70 pivoted near its lower end toa frame 71 by means of a pin 72. Arm 70 is provided with an extension 73 bent at an angle with the arm proper and mounted on portion 73 I provide an adjustable weight 74. Mounted to slide on frame 71 are two members 75 and these members are connected by cross-pins 76 and 77. Pin 76 projects through an opening 78 in arm 70 and pin 77 is designed to make contact with and be moved forward by a double eared cam 79 rotatable with the main drive shaft 28. The ears of cam 79 are of slightly different size, thus as shown ear a is of slightl. larger idly connected with arms 64 is likewise size than ear b; the purpose of ma ing the having a bent portion 81. The upper end of the fork 68 is secured to the end of portion 81 by means of an adjustable clam 82.

On the inner end of arm 80 I rovi e a gear-wheel 83 adapted to mesh with a rack 84 carried on thenpper end of a rod 85.

Rod 85 at its lower end is pivoted to the frame 71. This mechanism just described provides for the forward movements of the fork carrying a plate grasped on the inclined platform. The backward movement of arm 7 0 is effected by means of the weight 74`and the backward movement of the fork is effected by the movement of arm 70 cooperating with the rack 84.

In operation the sheets or plates are passed upwardly from the pile singly and successively to and between the rollers 46 and 47 by the friction wheels 56 and 57 acting at predetermined intervals upon the outer sheet or plate of the pile. After a sheet or plate passes rollers 46 and 47 it is conveyed by means of conveyer chains 45 between rollers 22 and 23 onto the inclined movable platform 32 and the plate held in position on said platform by means of the stops 67 until it is grasped by the movable fork 68 actuated by the mechanism described. Plates are passed alternately through the guideways in the flux-box by raising and lowering the platform 32 as above described,

and by the forward movement of the fork 68.

As above stated, the arm 70 is provided the forward movement of said members 75 as well as the in 76 and arm 70 are effected by means of t e cam 79 acting against the pin 77. It will be noted that the construction is such that a very slight forward move ment of the pin 76 acting in slot 78 of arm 70 will cause a considerable movement of the outer end of the arm 70, as particularly shown by Fig. 1.
